Re: Question regarding dcache flushing for arm(specifically armv8, cortex A53)

varun sharma <nurav251@...>
 

Hi Carlo,

Thanks for sharing your pr details...will review
any patch you submitted for dcache support in cortex a53 arm cpu?

I also did some homework, your insights will be helpful...


Thanks

I'm going to add support for that after
https://github.com/zephyrproject-rtos/zephyr/pull/30398 is merged.

Feel free to review it if you are willing to help :)

Question regarding dcache flushing for arm(specifically armv8, cortex A53)

varun sharma <nurav251@...>
 

Hi All,

I want to flush dcache in cortex a53 arm cpu, but it seems it is not implemented for arm in zephyr
I can't see any dcache_flush() implementation for arm..

I see it is only available for arc and x86, and not for arm...
pls share any reason it is not implemented for arm?

and if i want to add this, any pointers or pr/commit for that?

Thanks,
Nurav
Re: github org membership and permissions

Maureen Helm
 

Hi everyone,

Following up on this, I’ve now invited all of the collaborators currently listed in MAINTAINERS.yml to the zephyrproject-rtos GitHub organization and assigned them into a “collaborators” team. Membership in this GitHub team gives write access to the main zephyr repo, which is used for assigning labels and reviewers to issues/PRs. Merge rights are still restricted to members of the release team.

 

As before, you have the option to make your membership public, see the link below. Please let me know if you encounter any issues with repo access after this refactoring.

Subject: github org membership and permissions

 

Hi everyone,

This week the TSC approved the list of current maintainers in #24152. As a result, I have invited all of the approved maintainers to join the zephyrproject-rtos GitHub organization and assigned them into a “maintainers” team. Membership in this GitHub team gives write access to the main zephyr repo, which is used for assigning labels and reviewers to issues/PRs. Merge rights are still restricted to members of the release team.

 

Many maintainers previously had write access as an “outside collaborator”, which should no longer be necessary and has been removed. If you have lost access to the repo in this refactoring, then I have made a mistake and please let me know.

 

Also, membership in a GitHub organization is by default private, but you have the option to make it public:

Re: Canopen node nRF52832

"Karsten König <karsten.koenig.030@...>
 

Hi,

I am trying to remember why I added a separate CONFIG_CAN_MCP2515_MAX_FILTER next to the existing CONFIG_CAN_MAX_FILTER. I think there was a reason, but maybe I just misunderstood the kconfig system. Can you please open a github issue so we can discuss there?

I attached a small patch to drop CONFIG_CAN_MCP2515_MAX_FILTER in favor of CONFIG_CAN_MAX_FILTER, please apply that for further tests.
The rest of the comments in this email apply as well :-)


Cheers,
Karsten

Re: Canopen node nRF52832

Alexander Wachter
 

Hi Cristian,

Macros prefixed with CONFIG_ come from Kconfig.
Never try to set them in your application.
CONFIG_CAN_MAX_FILTER=13 goes to your mcp2515.conf
The CAN_MAX_FILTER is used in the MCP2515 driver,
and if you set it in some of your files, it won't end up in the driver.

As Marti already mentioned, you also need to allow MPU flash writes.

Cheers,

Alex

Hi all
I'm quite new on Zephyr and on CAN BUS so my question might have an easy or obvious answer.
I'm on Ubuntu and I'm using an nRF52DK nRF52832 (PCA10040) wired to a custom board equipped with a MCP2515 and a MCP2551 devices.
Is the samples\subsys\canbus\canopen suitable for an hardware like the one I'm using?
If so, any hints on how make this sample working?
1)
I can compile it  from command line with
west build -b nrf52dk_nrf52832 samples\subsys\canbus\canopen -DSHIELD=dfrobot_can_bus_v2_0 -DCONF_FILE=prj.mcp2515.conf
declaring in subsys\canbus\canopen\CO_driver.c (even though I thought it wasn't really need to declare this here)
#define CONFIG_CAN_MAX_FILTER 13
and prj.mcp2515.conf as attachment
Executing the project, I get the attached log file with a series of error messages and this stucks me here for this moment.
2)
Just to give some more info, I'd like to say that I did compile the samples/drivers/can from command line launching this
west build -b nrf52dk_nrf52832 samples/drivers/can/ -DSHIELD=dfrobot_can_bus_v2_0 -DCONF_FILE=prj.mcp2515.conf
and everything works as expected (tested using a CAN sniffer).
But it is not clear to me how to add in this project the CANOpen stack library.
Thanks in advance for the support
Kind regards
Crisian

Re: Canopen node nRF52832

Hi,

The MPU fault may be due to a missing CONFIG_MPU_ALLOW_FLASH_WRITE=y.

I don't know anything about CAN, though :).

Canopen node nRF52832

Cristian Anceschi <cristian.anceschi@...>
 

Hi all

I'm quite new on Zephyr and on CAN BUS so my question might have an easy or obvious answer.

I'm on Ubuntu and I'm using an nRF52DK nRF52832 (PCA10040) wired to a custom board equipped with a MCP2515 and a MCP2551 devices.

Is the samples\subsys\canbus\canopen suitable for an hardware like the one I'm using?
If so, any hints on how make this sample working?

1)
I can compile it  from command line with
west build -b nrf52dk_nrf52832 samples\subsys\canbus\canopen -DSHIELD=dfrobot_can_bus_v2_0 -DCONF_FILE=prj.mcp2515.conf 

declaring in  subsys\canbus\canopen\CO_driver.c (even though I thought it wasn't really need to declare this here)
#define CONFIG_CAN_MAX_FILTER 13

and prj.mcp2515.conf as attachment

Executing the project, I get the attached log file with a series of error messages and this stucks me here for this moment. 

2)
Just to give some more info, I'd like to say that I did compile the samples/drivers/can from command line launching this

west build -b nrf52dk_nrf52832 samples/drivers/can/ -DSHIELD=dfrobot_can_bus_v2_0 -DCONF_FILE=prj.mcp2515.conf

and everything works as expected (tested using a CAN sniffer).
But it is not clear to me how to add in this project the CANOpen stack library.

Thanks in advance for the support 

Kind regards
Crisian

Re: [Zephyr-users] Query regarding Bluetooth Controller Porting

Carles Cufi
 

+ devel list

Pankaj,

If you are using a dual-chip solution, then as long as you controller complies with standard HCI there is no "porting" to do whatsoever.
In order to better understand what you need, can you let us know which transport do you plan on using (UART/H4, 3-wire/H3 or SPI) and whether it is a single-mode or dual-mode controller?

Unless your controllers has special requirements it should all be a matter of configuring the right Kconfig options and Devicetree nodes.

Carles

ku7XtLCnOWo%3D&amp;reserved=0. The link’s talks about Bluetooth host in
detail and it was helpful. We want to use Dual Chip configuration mode
(use Zephyr Bluetooth host + custom Bluetooth controller support) .

From link it talks about various host only build configuration
o CONFIG_BT =y
o CONFIG_BT_HCI =y
o CONFIG_BT_CTLR =n


My query is in order to port custom controller what steps, build
configuration we need to take care of. If there is a link/document that
helps to describe porting of custom Bluetooth controller to Zephyr it will
be helpful.

IoT Long Term support Linux - Opening to the community of Redpesk@SEA the open source "Marine Grade Linux" by IoT.bzh.

Dominig ar Foll (Intel Open Source) <dominig.arfoll@...>
 

Hello,
As Marine requirement is very very close of any IoT (very) long term Linux requirement with high level of security and application isolation, I thought that this webinar from the Linux Fundation might be of interest to some of you...

The Marine Grade Linux project by IoT.bzh addresses smart ship provides a customized flavor of AGL that addresses marine specific requirements. For signaling, NMEA2000, CanOpen, Ethercat and Modbus were added. Cloud connectivity is designed to handle random connectivity with a balance of 4/5G and satellite data link. Some core marine services as nautical charts, safe routing, or radar are still under development and should be added in the near future. Last but not least, a 30 years old ship is pretty common and maintenance/update on 15 years is required.

This presentation exposes the outcome of the three marine projects IoT.bzh is currently developing for this industry. It starts exposing gaps in business models, then exposes some of the technical specificities (signaling, SOTA, LTS, …). Finally it introduces redpesk@sea the ready-to-use “Marine Grade Linux” version that IoT.bzh will propose as Christmas gift to the maritime open-source community.
